I based my measurements off an MTM shirt I ordered from a local MTM service and then added some extra safety margins to the shirt length and sleeves. This proved to be a winning strategy as my first order came out with an almost perfect fit. My custom collar instructions were followed with utmost precision, and I absolutely love the end result.
The cream ecru cloth is a good base cloth with a very pale yellow cast, just as the pictures show. I would perhaps not order the same cloth for a nicer, more formal shirt, as the cloth isn't all that exciting, but for the price (120 euros), I have no complaints whatsoever. I would have no qualms using the same cloth for an everyday shirt.
